Sea Creature or Plastic Bag?

This video was shot by underwater drillers of a jellyfish near their well at 5,000+ feet below the sea. Some people who viewed the video were puzzled by the floating creature, with suggestions that it may be a deep sea monster or a more mundate plastic bag.

Speculation was also rife that it may have been whale placenta or even the mythical creature Cthulhu. Experts have, however, confirmed that it is, in fact, a Deepstaria enigmatica, a jellyfish from the Ulmaridae family, first discovered in 1967 by F. S. Russel. The invertebrae is usually found in the South Atlantic ocean.
